Mybatis执行报错：There is no getter for property named “item” in class com.itzhimei.TestMobileListCondition

代码的实现目标是基于一个电话号码的List查询条件，去查询一组数据，但是报错如下：

org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'item' in 'class com.itzhimei.TestMobileListCondition'

我是要循环组装查询条件，使用mybatis的动态sql去拼装一个in的sql语法，代码如下：

<foreach collection="mobileList" item="mobile" separator="," index="index" open="(" close=")">
  #{item}
</foreach>

细心的朋友可能已经发现问题所在了，问题在于我定义集合中每个元素的别名是item=”mobile”，结果在foreache循环体中使用的却是“#{item}”，显然mybatis是找不到item别名的变量的，应该使用#{mobile}，代码改正如下：

<foreach collection="mobileList" item="mobile" separator="," index="index" open="(" close=")">
  #{mobile}
</foreach>	

这是一个粗心的问题，有时候陷入的思维定式，就需要一点时间去发现这个问题。
